At Computer Systems Design we specialize in Mac & PC virus and trojan removal with our virus removal service instead of selling you generic software that does not always remove your malware infection. Nowadays, viruses are much more advanced making them difficult to detect by even the best anti-virus programs like Symantec and McAfee. Amazingly, 95% of our clients have an up to date reputable anti-virus program, but today’s malware can easily bypass your anti-virus product and infect your computer, causing data loss, or even identity theft. Computer systems design's technical experts can manually remove your virus. If your computer has any of the following symptoms you may be infected with a virus, adware, spyware or other malware.
